Customer now crosses off bucket list and picks up other items

[erik-lance]

Customer should now have a complete flow in the grocery.

• [x] Customer chooses first item in bucket list
• [x] Customer goes to shelf of selected item
• [x] After picking up item, select new item
• [x] When bucket list empty, go to cashier

Apparently, a bug with the movement was involved.

• Customer was not going to cashier line if they finished their list at back row
• Movement doesn't halt after moving forward once
• Customer doesn't exit out of the right row sometimes
